Colorado group wants to ban sale of cellphones to kids under 13 years old

(FOX NEWS) - A Colorado group is looking to curb the sales of cellphones to children under 13 years old and officials in the state have cleared the language for a proposed ballot measure.

Parents Against Underage Smartphones, the backers of the move, would now need about 300,000 voter signatures for the legislation to make the 2018 ballot.

The ban would require cellphone retailers to ask customers about the age of the primary user of a smartphone and submit monthly reports to the Colorado Department of Revenue on adhering to the requirement.

Retailers who sell a phone for use by a pre-teen would get a warning for the first offense, but may face fines from $500 to $20,000 for continued violations, according to KDVR-TV.
